[GitHub] [spark] peter-toth edited a comment on pull request #29210: [WIP][SPARK-24497][SQL] Support recursive SQL query

   This is the static version of https://github.com/apache/spark/pull/23531 which means this PR doesn't do adaptive replanning in each recursive iteration, but the advantage is that the implementation comes with simplified code. Common relational DB implementations don't do replanning either.
   
   @maropu this is very close to what you suggested before, if you have some time please review.
   
   @maryannxue I think we can add adaptive support in a follow-up PR if needed.
